The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got a long 16-day window ahead, and I gotta be honest with you – it’s a tough stretch for surf at Kennebunk Beach. There’s a massive gap of flat, weak, or just plain messy conditions right through till nearly the end of the period. The first time we see anything with a bit of push is way out there.
The whole forecast is pretty bleak. Nearly every day has that “poor surf conditions” tag, and the wave heights are tiny – barely a ripple most days. The combined energy is almost always in the weak range, rarely cracking triple digits. You’re looking at a solid two weeks of pretty much nothing rideable.
The water temperature is running at 65°, which is a touch warmer than normal for this time of year – one of the few positives, but it doesn’t help the waves.
Now, the only real spike of energy comes on the 20th of September. We’ve got a bit of a pulse showing up Sunday morning with a swell around 6ft from the ENE, with a period of 7 seconds. The combined energy jumps to 295 (moderate) – easily the strongest we see in the whole forecast. It’s a short-period, windswell-type deal, though. The wind is a light cross-onshore, so it’ll be a bit bumpy, but at least it’s not a full gale. That said, 6ft is getting into the too-big-for-beginners zone, and the short period means it’ll be a bit soft and crumbly.
This swell carries into Monday the 21st, with similar size (6ft) and energy (269), but the wind is directly onshore from the SW, so it’ll be messy. By the afternoon it swings to a cross-shore from the NW, which cleans it up a bit, but the swell is on the way down.
So, if you’re desperate, the 20th of September is the only real standout. It’s the best of a bad lot. The swell direction from the ENE is not ideal for this sheltered spot – the optimum is from the ENE, so it’s actually a decent match for direction, but the short period and onshore wind will keep it average. Don’t expect any magic.
For the rest of the window? You’re looking at flat, choppy, or cross-shore junk. There’s a long gap of almost two weeks with nothing worth paddling out for. This isn’t unusual for a sheltered beach like this in a lull – it’s a blank run that’s pretty normal for the area.
Stay patient, and keep an eye on the forecasts. Conditions can change, but right now, it’s a waiting game.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
